(57) In a device designed to enhance the accumulation and retention of kinetic energy by the flywheels of engines and motors generally, and to optimize the successive use of such energy, the flywheel (2) turns in an airtight casing (4) connected to a vacuum pump (6) and maintained at negative pressure during operation in such a way that the resistance offered by air to the rotation of the flywheel is minimized.
